Thanks for the reply. I'm not in front of the robot right now, but I can post the full details tomorrow. My move_base and amcl configurations are not too far from default, but I will post them just in case. It is running on a desktop computer, dual core, 2.0 GHz. My map is 400x300 at 0.05 m/pixel. The average amcl delay is negative, as expected, but the max delay was 0.25 sec. I will post the full output tomorrow. Thanks again for your help! -Zac -- View this message in context: http://ros-users.122217.n3.nabble.com/Costmap2DROS-timeouts-and-poor-amcl-performance-tp2112835p2113359.html Sent from the ROS-Users mailing list archive at Nabble.com.
